In this paper, we describe an efficient method for audio matching which performs effectively for a wide range of classical music. The basic goal of audio matching can be described as follows: consider an audio database containing several CD recordings for one and the same piece of music interpreted by various musicians. Then, given a short query audio clip(More)
We present an efficient and robust multiscale DTW (Ms-DTW) approach to music synchronization for time-aligning CD recordings of different interpretations of the same piece. The general strategy is to recursively project an alignment path computed at a coarse resolution level to the next higher level and then to refine the projected path. As main(More)
One major goal of structural analysis of an audio recording is to automatically extract the repetitive structure or, more generally, the musical form of the underlying piece of music. Recent approaches to this problem work well for music where the repetitions largely agree with respect to instrumen-tation and tempo, as is typically the case for popular(More)
Significant digitization efforts have resulted in large multi-modal music collections comprising visual (scanned sheet music) as well as acoustic material (audio recordings). In this paper, we present a novel procedure for mapping scanned pages of sheet music to a given collection of audio recordings by identifying musically corresponding audio clips. To(More)
We propose a new type of audio feature (HFCC-ENS) as well as an unsupervised method for detecting short sequences of spoken words (key-phrases) within long speech recordings. Our technical contributions are threefold: Firstly, we propose to use bandwidth-adapted filterbanks instead of classical MFCC-style filters in the feature extraction step. Secondly,(More)
